culates the air currently within the vehicle.
During AUC operation, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>Indicator lamps off: outside air flows into the
vehicle.
>Left indicator lamp on, AUC mode: the sys-
tem recognizes pollutants in the outside air
and blocks the flow of air when necessary.
The system then recirculates the air cur-
rently within the vehicle. Depending on the
air quality, the automatic system then
switches back and forth between outside air
supply and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the outside
air supply into the vehicle is shut off contin-
uously. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. The recirculated-air mode should not
be used over a sustained period of time, other-
wise the air quality inside the vehicle will deteri-
orate.<
Rear window defroster
When the rear window defroster is
activated, the indicator lamp
comes on. The rear window
defroster switches off automatically.
You can have your vehicle set so that the
rear window defroster switches on auto-
matically. It is then switched on at outside tem-
peratures of less than approx. +397/+46
within 5 minutes of the engine start.<
Ventilation
The air vents for the upper body area can be
adjusted:
1Serrated dials
Serrated dials for opening and closing the
vent outlets through an infinitely-variable
range.
2Levers
Selector levers for airflow direction.
3Serrated dial
Use this serrated dial to adjust the amount
of cool air that is added to the airflow
emerging from the vent outlets for the
upper body.
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter*
The built-in microfilter removes dust and pollen
from the incoming air. The activated-charcoal
filter provides additional protection by filtering
gaseous pollutants from the outside air. This
combined filter is replaced when maintenance
is performed by your BMW Sports Activity Vehi-
cle Center. A substantial reduction in air supply
indicates that the filter should be replaced
before normal maintenance.

Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to
a fire, resulting in serious personal injury and
property damage.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. portable
phones, in the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
Inside rearview mirror, automatically
dimming*

The inside rearview mirror contains two photo-
cells that control the automatic dimming func-
tion. One is integrated into the mirror glass, the
other is located on the back of the mirror.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers on the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page28, as
otherwise they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor as otherwise dam-
age could result from undesired wiper activa-
tion, refer to page39.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle's
engine, the electrical systems and the trans-
mission may be damaged.<
Use handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise greater clutch
wear will result.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. The best way to brake is to apply
maximum pressure to the brake pedal during
emergency: panic braking. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.

Washer fluid
Headlamp* and windshield washer
system
The antifreeze for the washer systems is
flammable. For this reason, keep it away
from sources of flame and store it only in its
original containers. Store it so that it is inacces-
sible to children. Always observe the instruc-
tions for use provided on the containers.<
We recommend that you mix the washer
fluid before adding it to the reservoir.<
Capacity of the windshield washer system:
approx. 3.2 US quarts/3 liters.
Capacity for equipment with headlamp washer
system: approx. 6.9 US quarts/6.5 liters.
Fill with water and, if required, with an antifreeze
additive according to manufacturer's recom-
mendations.
Engine oil
Engine oil consumption depends on driving
style and operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up red:
Stop the vehicle immediately and
switch off the engine. Check the engine
oil level; top off as required. If the oil level is cor-
rect: have the system checked immediately.
Do not continue driving. The engine could
be damaged because of inadequate lubri-
cation.<
Engine oil level
The warning lamp lights up yellow while
driving:
The oil level is at the absolute mini-
mum. Add engine oil as soon as possible. Until
then, do not drive more than approx. 30 miles/
50 km.
The warning lamp lights up yellow after
the engine is switched off:
Top off engine oil at the earliest oppor-
tunity, e.g. when refueling.
Engine oil sensor
The warning lamp lights up yellow
within 20 seconds after starting the
engine:
The oil level sensor is defective. Have checked
as soon as possible.
Checking oil level
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Switch off engine.
3.After approx. 5 minutes, pull the dipstick out
and wipe it off with a clean lint-free. cloth,
paper towel, or similar material.
4.Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
5.Push the oil dipstick into the dipstick tube
as far as possible again.
The oil quantity between the two marks of the
dipstick is approx. 1.1 US quarts/1 liter.
